“…As a great attention is devoted to the risk assessment of domino effect occurrence, the accuracy of the evaluation relies on the hypotheses and the adequacy of the models developed for each constitutive part of the whole domino effect sequence (Cozzani, Tugnoli, & Salzano, 2007, in press;Gubinelli, Zanelli, & Cozzani, 2004;Hauptmanns, 2001aHauptmanns, , 2001bHolden, 1998;INERIS, 2002aINERIS, , 2002bINERIS, , 2004Khan & Abbasi, 1999, 2001a, 2001b, 2001cKhan, Husain, & Abbasi, 2002;Lees, 2005;Mé barki et al, 2005; Mé barki, Ami Saada, Nguyen, Mercier, & Reimeringer, 2007;Mé barki, Mercier, Nguyen, & Ami Saada, 2009;Mercier, Boulanger, Mé barki, Brunet, & Reimeringer, 2006;Nguyen, Mé barki, Mercier, Ami Saada, & Reimeringer, 2006;Pula, Khan, Veitch, & Amyotte, 2006Tugnoli, Khan, Amyotte, & Cozzani, 2008a, 2008b:…”

“…According to the literature, the initial velocity estimation is carried out on the basis of the energy released in the tank explosion, in accordance with the models presented in [13][14]. The kinetic energy corresponding to the initial velocity of a fragment is estimated on the basis of the share of explosion energy [15]. The factor α of the explosion energy share transferred to the fragment is between 20% and 50%; this factor was defined by Hauptmanns et al [10].…”

The paper analyses the fragmentation of a horizontal cylindrical tank caused by the effect of boiling liquid expanding vapour explosion (BLEVE). A fragmentation model for identification of kinematic parameters is proposed. The originality of the model lies in the introduction of initial acceleration. Using this model, the initial velocity can be assessed without knowing the values of explosion energy and the mass of fragments. The application of this model reduces the uncertainty in assessing the range of fragments and the risk of fragmentation. The initial acceleration of fragments generated in an explosion is assessed according to the geometry and type of the tank material. The initial acceleration, which does not depend on the kinematic parameters of the constant wall thickness of the tank, allows a reliable assessment of the launch angle of a fragment. Characteristic forms of the fragment trajectory are identified, depending on the aerodynamic and thrust acceleration coefficients, and probability distributions of the fragment ranges are given. Relevant factors in the assessment of fragmentation hazards include the trajectory of a fragment, the height of a target and its distance from the tank. It was concluded that aerodynamic fragments at distances of up to 50 m are not a danger to targets of up to 15 m high. Fragments with high air resistance and low thrust can endanger targets of the same height at distances of over 200 m. The presented fragmentation model includes the effect of heating due to the BLEVE effect and can be applied to all types of tanks.

“…The models of BLEVE effects cover blast, fireballs, and projection of fragments (projectiles) (e.g., CCPS 1994;Casal 2007). Most of these models are strictly deterministic; some models include probabilistic elements (Hauptmanns 2001;Vaidogas 2006;Mébarki et al 2009;Nguyen et al 2009). The key input information of them is of geometric nature.…”

Road tankers used for the transportation of flammable liquids and liquefied gases can be involved in accidents which escalate into fires and the so-called boiling liquid expanding vapour explosions. The damaging effects of these phenomena on roadside property depend on the position and orientation of exploding tanks in relation to vulnerable roadside objects. This study presents a simulation-based approach to the prediction of the position of road tank explosions. The position is expressed by longitudinal and transverse rest position of an exploding tank as well as departure angle of the tank. As a part of this study, data on transverse rest position and departure angle was collected and used to fit probability distributions which express uncertainties in these circumstantial characteristics of road tank accidents. It was found that data on the longitudinal rest position is difficult to obtain and modelling this accident characteristic will have to rely on a subjective specification of probability distributions. Such distributions can be chosen by applying approaches used in the field of quantitative risk assessment. Probability distributions, partly subjective and partly based on hard data, are applied to simulate values of potential explosion coordinates. The simulation results have the premise to be applied to forecasting mechanical and thermal effects of explosions on road and assessing damage from them. A case study used to evaluate the performance of the models proposed in this study is presented in the second part of the paper.
